When the Green Bay Packers break the huddle on offense and come up to the line of scrimmage, most of the attention is on quarterback Aaron Rodgers and anything he may yell out or signal - a check, an audible, the cadence - before the ball is snapped.

But Rodgers' offensive mates are paying just as much attention to another guy feeding them vital pre-snap information, and that's center Scott Wells.

In the middle as the de facto captain of the offensive line, Wells is in charge of making the initial declaration of the pass protection scheme before every snap to the rest of the offense, including the linemen, tight ends and running backs. It's a call he makes based on the defensive front he sees, and one he can or must adjust depending on how the defense might shift, blitz, or otherwise change up its attack.
